Xeon™ Processor 3400 Series

Key Features of the Intel®Xeon™ Processor 3400 Series (codenamed “Lynnfield”)

 Intel®Core™ Microarchitecture (“Nehalem”)

These processors offer users the benefits of the latest technology – Nehalem architecture – in a single-processor
configuration.

 Intel® Turbo Boost Technology

Turbo Boost delivers additional performance automatically when needed by taking advantage of the processor's
power and thermal headroom. This enables increased performance of both multi-threaded and single-threaded
workloads.

 Intel®Hyper-Threading Technology

Hyper-Threading Technology, available with most Xeon 3400 Series processors, allows thread-level parallelism,
resulting in more efficient use of pr oces sor r esour ces. With higher processing throughput, you enjoy subst ant ially
improved performance.

 Integrated Memory Controller (IMC) with 2 Channels DDR3 Memory

The move to DDR3 memory offers increased performance due to higher m emory speeds, and reduced power
consumption compared to FB-DDR2 m emory operating at the same speed. The 3400 Series supports up to 4
ECC / Non-ECC UDIMMs or 6 RDIMMs.

 Integrated PCI Express I/O

16-lane PCI Express 2 port enables all input/out put and manageability functions to be handled by a single chip.
Flexible configuration options include 1x16, 2x8, or 4x4.

Xeon™ Processor 3400 Series

Platform capability (6 DIMMs):

• Up to 2 channels per CPU

•

Up to 3 DIMMs per channel

Memory types supported:

• DDR3 1333, 1066, and 800

• Registered ECC (RDIMM) and Unbuffered ECC (UDIMM)

•

Single-rank (SR), dual-rank (DR), quad-rank (QR)

System memory speed (i.e. the speed at which the memory is actually
running) is set by BIOS depending on:

• CPU capability

• DIMM type(s) used (memory speed, U/RDIMM, SR/DR/QR)

•

Number of DIMMs populated per channel

Both channels in a system will run at the fastest common frequency:

• Example: If you populate 1 DIMM at 1333 MHz in Channel 1, and 1 DIMM at 1066

MHz in Channel 2, both DIMMs will run at 1066 MHz.
